Nokia's largest shareholder Solidium raises stake to over 5%

Nokia Oyj's largest investor, the Finnish government's investment firm Solidium, has increased its stake to just over 5% for the first time, from about 4.8%, according to a regulatory filing. Nokia, which axed its dividend after a profit warning last October, has been scripting a turnaround by keeping a lid on costs and addressing shipment delays in its attempt to compete with rivals such as China's Huawei and Sweden's Ericsson.
